SPECIFICATION forming art of Letters Patent No. 646,404, dated March 27,"1900. Application filed October 31,1899. Serial No. 735,350, (Nomodel.)

producing acetylene gas, especially constructed for the purpose of usingcandles, molded sticks', or the like made of calcium carbid.ThlS-ilIlPlOVBd apparatus can be recharged while working and withoutoccasioning any escape of gas. I will now describe it with reference tothe accompanying drawings, in

Figural isavertical. section. Fig. 2 is a View, half plan and halfhorizontal section, on line 2 2, Fig.1. Figs. 3, 4, and5 represent invertical section the various parts of a can bid box or chamber; and Fig.6 is a sectional view on the line 6 6, Fig. 5.

. My apparatus consists of .a tank or vessel a,

in which are placed the regulating-bell b and the various carbidchambers or containers 0.0.

The respective positions of these various parts of the apparatus can bevaried. Usually the 'bellis placed at the center and the carbid- 3chambers around the latter. Each of the carbid-chambers consists of .anoblong or tubular bell c, in which can be engaged by its lower opening atube (I, intended to receive the carbid stick or candle f, this latterbeing supported by a grid r. As seen more clearly in Fig. 5, the'tubc dis open at both ends and toward its lower extremity has two oppositeslots or notchesc-ut into it, leaving side walls covered by a small bellg, which is free and merely rests upon the lower collar'h of the tube d;bell c by means of any suitable device-for inst'ance,by a bayonet-jointor by the hook-f catchesi. (Shown'on'the drawi'ngsz) In itsupperp'ortion' the bell c is divided by a grid This tube d can besecured-tothe or grating 7c, and above the said grid itcon mu nicateswith a vertical tube j, which is carried by the bell, this tubebeingclosed at the top and open'at the bottom. As indicated in Fig. 3,the space above the grid 7; may concan be supported. in the vessel a bymeans of a flange or shoulder I resting upon the cover a at the upperpartotthe vessel, the said cover being provided with openings to receivethe various carbid-chainbers c 0. These latter can thus be easilyinserted and withdrawn.

The bottom of the tank a is preferably formed by a partition m-,which isiu'clined'or funnels .tain' a suitable gasepurifying material. Each oithe bells c, with all its working parts,-'aswell as the tube j fixedthereto, as explained,

shaped, and has at its lowest part a valved outlet m th ough which theresiduum. may berernoved. Beneath the-partition m isa closed chamber m,toward the lower part of which thevertical tubes n n deliver the gas.

from the chambers c. This chamber m is supplied with water to a pointabove the discharge-points of the tubes, so as to constitute a waterseal andwashing-chamber. These tubes n are of a sufficient height whenthe chambers c are in place to enter the tubes up to the upperportion.The dilterent chain.- bers c are constructed in this manner, and

'with the tube jof eachof them corresponds pended. from the top of thebell by a central tube 1; and constitutes a displacement-body. Theweight of this receiver 1) can be regulated as desired by introducingWater, granulated lead, &c., into the. same through a pipe 'q; 7

. whose otherend'projects through the crown of the bell. 1 Into theupper part of this gov-' ernor-bell b there delivers a tube '2", whichtoo opens from theupper part of the chambertn, Y

above the level of the water therein. In the present instance this gas-tube ropens'into the central tube 19, which carries the receiver I 1the chamber being in the. positioushownon p, and-has suitable ontlets'for the gas into I cook it for the escape of air. 4

The working of the apparatusis as follows:

Each o'fithe chambers cis furnished 'th the} gas-generatin g substancein the form stick,

cartridge, or candle f, the various parts of the drawings and as abovestated. These chambers cc are placed, in thavessel a, this latter beingfilled with water up to a certain.

height. The level oii this water; tends to equalize itself in thevessel-ct, inthe bellrb, andin,thecarbid-chamberscc. Consequently whenthe water comes in contact with the candles f gas is given of. If theloose bellcov ers g are used over the tubesd, the first effects'of. thegeneration of the gas will be to depress the water-level in the'co versor to raise these covers g until the gas can escape around their loweredges and up into the bells c. The gas rising in the bells c. escapes bythe tubes j and it (after havingpassedfiif necessary, in contact withthe desiccating-material placed above the grids k) and is delifts withit the mass 19, which, being of a chambers c c.

' ceases, and the pressure diminishing by the 1 redesoends'.

livered into the midst ofthewater contained in the chamber m, throughwhich water it bubbles. It collects in the upper portion of this chamberm and passes ;t rough tube 5', whence it reaches the governor-belib,which it fills and raises. This bell being so raised fairly-considerablevolume and partly standing out of the water, consequently displaces amuch less quantity of water. that the level of water in the hell I) islowered aswell as in the vesselfa and in the carbid- The carbid sticksno longer dipping into the water, the production of gas consumption ofthe" gas the governor-bell b The receiver 10 is thereupon immersed to agreater extent, displacing a greater quantity of water and causing arise in level'in the chambers c, the candles again dipping into thewater and the production of gas again commencing. This succession ofphenomena will be effected in a continuous manner, and the production ofgas thus takes place regularly, according to consumption.

It will be remarked that in case of an ex cessive production of gasthedifl'erent chain bers or bells'c are raised a certain height, for theyare held freely in the openings inthe cover a, and thus increase thecapacity of the apparatus occupied by the gas. Also in each of the.chambers c the bell gin'tervenes as a safety device, for in case of anexcessive production the water is at first driven back from within thehell 9 to its outside-that is quent in the chamber cthe candle fconseyno longer dipping into the water. It will be observed that with thisapparatosay i It follows ms the recharging of the generato'nwith thegasproducing substance can be effected without any escape of gas. Byraising up any one chamber 0 for this purpose the gas-tube j isdisengaged from the tube n, and thislatter is then in communication withthe atmosphere; but the gas contained inthe chamber m' drives back' thewater' in this tube t a 7 height corresponding with the pressure. I"mayobviously modify the construction of this apparatus without departingfrom the spirit of my invention.
